Specification of Letters Patent.

Patented'Sept. 10, 1912.

Application filed May 26, 1911. Serial .No. 629,,597.

To all whom it may concern:

Be it known that I, THOMAS PnrERsoN, a citizen of the United States,residing at Duluth, in the county of St. Louis and State I of Minnesota,have invented new and useful Improvements in Mop-lNringers, of which thefollowing is a specification.

The invention relates to the class of mop wringers.

The primary object of the invention is the provision of a pail in whicha mop may be wrung, so as to relieve the same of any ex cess or surplusamount of water by means of rollers operated by foot leverage, the pailbeing supported on casters whereby it may be conveyed in a convenientmanner from one locality to another, thereby obviating the necessity ofcarrying the pail in the hand gt a user, thus preventing the marring ofa oor.

Another object of the invention is the provision of a wringer in whichthere are arranged wringer rollers disposed in pairs transversely onepair in superposed relation to the other, the rollers of one pair beingstationary, while the rollers of the other pair being adapted toapproach toward and retreat from each other for the proper wringing of amop, so that water may be squeezed therefrom and deposited within thepail.

With these and other objects in view, the invention consists of theconstruction, combination and arrangement of parts, as will be morefully described hereinafter, illustrated in the accompanying drawings,and pointed out in the claims hereunto appended.

In the drawings: Figure 1 is a side elevation of a mop wringerconstructed in accord ance with the invention. 2 is a top plan view.Fig. 3' is a vertical longitudinal sectional view. Fig. 4 is a sectionalview on the line 1- 1 of Fig. 1. Fig. 5 is a fragmentary perspectiveview of the keeper rack. Fig. 6 is an enlarged fragmentary view of oneroller and its sliding bearings, the latter being in section showing indetail its connection with the body of the pail.

Similar reference characters indicate corresponding parts throughout theseveral views of the drawings.

Referring to the drawings by numerals, 5 designates the body of a pailfor receiving water, the pail being preferably substan tially squareshaped and is constructed from metal such as galvanized iron, the upperend edge of the side walls of the pail being provide'd with the usualead -6 forming a track for a purpose, as will be hereinafter more fullydescribed.

Mounted transversely at the mouth edge of the pail are rotatable rollers7, the same being arranged in spaced relation to each other and areprovided with reinforcing sleeves or caps 8, the rollers beingpreferably formed from hard wood, and these caps engage with oppositereduced ends of the rollers. The caps or sleeves 8 are provided withstud journals 9 engaging stationary bearings 10 suitably mounted inalining pairs upon the opposite sides of the pail contiguous the mouthedge thereof, whereby the rollers will serve for wringing a mop whenbeing withdrawn from the pail for freeing it from an excess or surplusamount of water. In superposed relation to the rollers 7 and at rightangles to them are rotatable wringer rollers 11 having reduced ends engaged by reinforcing sleeves or caps 12 pro vided with stud journals 13,the latter being mounted in slidable bearings 14: formed with grippingcars 15 loosely embracing the beaded edge 6 of the pail, the bearingsalso being provided with laterally extending journal lugs 16 engagingswinging arms or levers 17 which latter are connected at their free endsby means of pivots 18 to the adjacent ends of links 19, which have theiropposite ends pivotally connected to links on a foot bail or yoke, aswill be hereinafter more fully described. This foot bail or yokecomprises a U-shaped frame 20 formed from a single piece of material,the extremities of which are connected to the opposite side walls of thepail by means of pivots 21,

the frame being provided, spaced from the pivoted end thereof, withoutwardly extending pivot lugs 22, to which are connected upstandinglinks 22, having at their upper ends branches to form parallel ears 22"which are pivoted, as at 23, to the links 19. The levers or arms 17cross each other and are provided with elongated guide slots 23, inwhich are engaged the guide pins or lugs 24 fixed to and projectingoutwardly laterally from opposite faces of the side walls of the saidpail, the lugs 24: being spaced a suitable distance from the upper edgeof the body of the pail and by this arrangement, the rollers are adaptedto move toward and away from each other on movement of the foot bail oryoke for the wringing operation. This yoke or bail 20 is provided with astep or foot piece 25, the same being adapted for movement in the pathof a locking rack comprising a bedframe 26 provided with a toothed rack27, the teeth of which being engaged by the step or foot piece 25 tohold the rollers 11 in adjusted relation when moved toward each otherafter downward pressure has been relieved on the foot yoke or bail.

Suitably mounted at the bottom of the pail near the corners thereof arefixed casters 28, the latter being rotatably supported v 1n bearings 29secured to angle bars 30, the

latter being secured to the bottom of the pail for strengthening thesame, and by means of these casters 28, the pail may be moved upon afloor from one locality to another.

Suitably attached to the mouth of the pail is a loop handle or bail 31,whereby the said pail may be lifted by hand and carried from one polntto another when desired.

At each side of the pail 5 is arranged an inverted Vl-shaped resilientleaf spring member 32, one end of which is connected to one of thelevers or arms 17, while its opposite end frictionally engages the otherlever 17. Thus it will be seen that when the bail 20 is released, thesaid levers 17 at their lower ends will be spread apart, thereby causingthe separation of the rollers 11 to bring the same into normal positionspaced from each other.

By the arrangement of the wringer rollers, a mop may be wrung forsqueezing therefrom excess or surplus water, the mop being dipped intothe pail in the ordinary well-known manner and withdrawn therefrombetween the said wringer rollers when it is desired to wring the same.

What is claimed is:

l. The combination with a pail, of means slidably engaged with its mouthedge, wringer rollers journaled in the said means, a yoke having limbspivoted to opposite sides of the pail, toggle connections between thelimbs of the yoke and the said means, a keeper rack fixed to the pail,and a foot stirrup swingingly connected to the yoke and adapted forlocking engagement with the said keeper rack when moved into the path ofthe same.

2. The combination with a pail, of slidable bearings connected with theupper edge thereof, rotatable wringer rollers journaled in saidbearings, crossing levers connected with said slidable bearings, a footyoke pivoted to the pail and having connection with said crossinglevers, the said crossing levers being provided with elongated slots,guide lugs fixed to and projecting from the pail into the said slots,stationary bearings fixed to the pail, and spaced wringer rollersjournaled in said stationary bearings beneath the movable rollers.

In testimony whereof I aflix my signature in presence of two witnesses.

THOMAS PETERSON.
